Description

Technical Field

[0001] This utility model belongs to the field of fabric laying machine technology, and more specifically relates to a fabric pressing mechanism for a fabric laying machine. Background Technology

[0002] Currently, when laying fabric in one direction, a pressing device is needed to hold down the fabric end to ensure the flatness of the fabric. The traditional method is to use a needle-cloth pressing method, but this method can easily damage the fabric. Therefore, a pneumatic or electric device is used to drive the pressing device to press the fabric, but this increases the power required for the entire laying equipment, which is not conducive to energy conservation and emission reduction. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fabric pressing mechanism for a fabric laying machine, which eliminates the need for electric or pneumatic power during the pressing and loosening process, thereby reducing energy consumption.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fabric pressing mechanism for a fabric spreading machine, wherein the fabric pressing mechanism is disposed at one end of a fabric spreading table, the fabric pressing mechanism includes support frames located on both sides of the fabric spreading table, sliders are vertically connected to the support frames, a rotating shaft is rotatably connected between the two sliders, a first drive plate is disposed on the rotating shaft, a pressure plate is disposed on the first drive plate, a second drive plate is disposed on the slider, the second drive plate is located below the first drive plate, a support plate is disposed on the cutting device of the fabric spreading machine, and the support plate is located in front of the cutting device in the fabric spreading direction, a first drive block and a second drive block are disposed on the support plate, the first drive block is located below the first drive plate, and the upper end surface of the first drive block is located above the lower end surface of the first drive plate, the second drive block is located below the second drive plate, and the upper end surface of the second drive block is flush with the lower end surface of the second drive plate, a torsion spring is disposed between the rotating shaft and the slider, the torsion spring has a torque that keeps the first drive plate and the second drive plate horizontal, and a positioning mechanism is disposed between the slider and the support frame.

[0005] Furthermore, the support plate is provided with two first driving blocks, which correspond to the two ends of the first driving plate in the width direction of the spreading table.

[0006] Furthermore, there are two of each of the second drive plate and the second drive block. The two second drive plates are located on the two sliders respectively, and the two second drive blocks are located at the two ends of the support plate in the width direction of the fabric spreading table.

[0007] Furthermore, the positioning mechanism includes a gear rotatably connected to the support frame and a rack located on the slider. The gear meshes with the rack, and a ratchet is provided on the gear. A pawl corresponding to the ratchet is hinged to the support frame.

[0008] Furthermore, a plurality of guide rods are slidably connected to the first drive plate, the pressure plate is located on the guide rods, and a spring is provided on the guide rods, the spring providing downward pressure to the pressure plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The fabric spreading machine moves toward the support frame. When the first drive block contacts the first drive plate, it lifts and rotates the first drive plate, while simultaneously causing the pressure plate to rotate and rise until the fabric spreading machine moves to the starting point of the fabric spreading process. At this time, the second drive block contacts the bottom of the second drive plate. Then, the cutting device raises the laying height by one layer (generally the thickness of one layer of fabric), raises the slider, and causes the pressure plate to be vertically raised by one layer of laying height. Then, the fabric spreading machine moves away from the support frame and begins to spread the fabric. When the first drive block retracts, the pressure plate resets and presses down on the fabric end again. After the fabric spreading machine reaches the end point of the fabric spreading process, the cutting device cuts the fabric. The fabric spreading machine then returns to the starting point of the fabric spreading process and raises the pressure plate and then the slider again, repeating the cycle until the fabric spreading is completed. The pressing and releasing process does not require the use of electric or pneumatic power, reducing energy consumption. Attached Figure Description

[0018] Reference Figures 1 to 5 The present invention will be further described below.

[0019] A fabric pressing mechanism for a fabric spreading machine is disclosed. The pressing mechanism 2 is located at one end of the fabric spreading table. The pressing mechanism 2 includes support frames 3 located on both sides of the fabric spreading table. Slider 4 is vertically connected to the support frames 3. A rotating shaft 5 is rotatably connected between the two sliders 4. A first drive plate 6 is mounted on the rotating shaft 5. A pressure plate 7 is mounted on the first drive plate 6. A second drive plate 8 is mounted on the sliders 4 and is located below the first drive plate 6. A support plate 10 is mounted on the cutting device 9 of the fabric spreading machine 1, and the support plate 10 is located in front of the cutting device 9 in the fabric spreading direction. The support plate 10 is provided with a first driving block 11 and a second driving block 12. The first driving block 11 is located below the first driving plate 6, and the upper end surface of the first driving block 11 is located above the lower end surface of the first driving plate 6. The second driving block 12 is located below the second driving plate 8, and the upper end surface of the second driving block 12 is flush with the lower end surface of the second driving plate 8. A torsion spring is provided between the rotating shaft 5 and the slider 4. The torsion spring has a torque that keeps the first driving plate 6 and the second driving plate 8 horizontal. A positioning mechanism is provided between the slider 4 and the support frame 3.

[0020] Specifically, the cutting device 9 is vertically connected to the end of the fabric spreading machine 1, and the fabric outlet is located on the cutting device 9, so that the fabric spreading height and the cutting position of the fabric are always consistent, which is the existing technology.

[0021] Specifically, the support frame 3 is located on one side of the fabric laying table in the direction of the starting point of the fabric laying.

[0022] like Figures 1 to 5 During the fabric laying process, the fabric laying machine 1 moves towards the support frame 3. When the first drive block 11 contacts the first drive plate 6, it can lift and rotate the first drive plate 6, simultaneously driving the pressure plate 7 to rotate and lift until the fabric laying machine 1 moves to the fabric laying starting point. At this time, the pressure plate 7 is lifted above the fabric laying starting point, and the second drive block 12 contacts the lower part of the second drive plate 8. Then, the cutting device 9 on the fabric laying machine 1 raises the laying height by one layer (generally the thickness of one layer of fabric), thereby synchronously driving the second drive plate 8 through the second drive block 12 to lift the slider 4 and make... The pressure plate 7 is vertically raised to the laying height of one layer. Then the fabric laying machine 1 moves away from the support frame 3 and begins to lay the fabric. When the first drive block 11 retracts, the torque of the torsion spring drives the rotating shaft 5 to reset and rotate, so that the pressure plate 7 presses down on the fabric end again. After reaching the end of the fabric laying, the cutting device 9 cuts the fabric. The fabric laying machine 1 then returns to the starting point of the fabric laying and once again raises the pressure plate 7 through the first drive block 11, and then raises the slider 4 through the second drive block 12. This cycle repeats until the fabric laying is completed. The pressing and loosening process does not require the use of electricity or pneumatics, reducing energy consumption.

[0023] Specifically, the support frame 3 is provided with a guide rail (or guide groove), and the slider 4 is provided with a guide groove (or guide rail) corresponding to the guide rail (or guide groove), thereby improving the stability of the slider 4 as it rises and falls.

[0024] In this preferred embodiment, the support plate 10 is provided with two first driving blocks 11, which correspond to the two ends of the first driving plate 6 in the width direction of the spreading table. That is, the first driving blocks 11 at both ends contact the first driving plate 6 at the same time, causing it to rotate and be lifted.

[0025] Of course, if the size allows and there is no interference, multiple first drive blocks 11 can be set between the two first drive blocks 11 to lift the first drive plate 6 and ensure the stability of the first drive plate 6 when it is lifted.

[0026] Specifically, multiple reinforcing ribs can be provided on the upper surface of the first drive plate 6 to improve the strength of the first drive plate 6.

[0027] Specifically, a support rod can be set between the two support platforms, and a bearing seat can be set on the support rod so that the rotating shaft 5 passes through the bearing seat, thereby providing support for the rotating shaft 5.

[0028] In this example, preferably, there are two second drive plates 8 and two second drive blocks 12. The two second drive plates 8 are located on the two sliders 4 respectively, and the two second drive blocks 12 are located at the two ends of the support plate 10 in the width direction of the fabric spreading table, so as to avoid interference with the rotation and lifting of the pressure plate 7.

[0029] like Figures 1 to 5As shown, in this preferred embodiment, the positioning mechanism includes a gear 13 rotatably connected to the support frame 3 and a rack located on the slider 4. The gear 13 meshes with the rack, and a ratchet 14 is provided on the gear 13. A pawl 15 corresponding to the ratchet 14 is hinged to the support frame 3.

[0030] Specifically, when the slider 4 rises, the rack drives the gear 13 to rotate, causing the ratchet to rotate. This causes the pawl 15 to engage with another ratchet tooth on the ratchet wheel 14, thus fixing the height of the slider 4 and preventing it from sliding down and pressing excessively on the fabric. It also prevents interference between the second drive plate 8 and the second drive block 12, which would affect the lifting of the pressure plate 7.

[0031] Specifically, a torsion spring is provided on the rotating shaft of the pawl 15, and the torsion spring ensures that the pawl 15 is always in contact with the ratchet 14.

[0032] Specifically, the pawl 15 is provided with a handle 16. By rotating the handle 16, the pawl 15 can be separated from the ratchet 14, thereby releasing the slider 4.

[0033] Specifically, if the thickness of a single layer of fabric is small and the spacing between the ratchet teeth on the ratchet 14 is too large, the ratchet 14 and the gear 13 can be separated (not on the same axis), and then a reduction gear 13 can be set between them so that the height of the slider 4 when it rises one layer can allow the pawl 15 to cross at least one ratchet tooth.

[0034] like Figures 1 to 5 As shown in this example, preferably, a plurality of guide rods 17 are slidably connected to the first drive plate 6, the pressure plate 7 is located on the guide rods 17, and a spring 18 is provided on the guide rods 17, the spring 18 providing downward pressure to the pressure plate 7.

[0035] Specifically, when the pressure plate 7 presses on the end of the fabric, it provides downward pressure through the spring 18. At the same time, when the pressure plate 7 is raised vertically and then pressed down, it exerts the same downward pressure on the fabric.

[0036] Specifically, when the first drive plate 6 rotates and rises, the spring 18 will release some of its elastic force. The end of the guide rod 17 is provided with a fixing plate, which contacts the first drive plate 6 at this time, thereby preventing the spring 18 from releasing all its elastic force.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
